WebAlexa Jacob. The Endoplasmic Reticulum in a eukaryotic cell is the transport network of the cell and it extends from and connects the nuclear membrane to the plasma membrane of a cell. But then whenever we draw a diagram of a typical plant or animal cell, we never extend it to the plasma membrane- we always leave it somewhere in the cytoplasm. http://www.bio.utexas.edu/faculty/sjasper/bio212/eukaryotes.html hillary 2000
